Atlanta is starting Saturday on a quiet note, with clear skies over the metro and temperatures near 52F at Hartsfield-Jackson as of 5:40 a.m. EDT on March 14, 2026. Sunshine will rule the day and send afternoon highs into the mid-70s, a classic "get outside while you can" kind of day before rain pushes in Sunday and a much more serious round of storms targets the area Monday.
Afternoon: Sunny And Unseasonably Warm
Saturday, March 14, 2026, looks bright, dry and unseasonably warm, with a high near 76F and a light west breeze around 0 to 5 mph. It is the kind of afternoon made for parks, patios and knocking out errands without worrying about getting soaked.
According to the National Weather Service in Peachtree City, humidity should stay reasonable through the afternoon before southerly return flow starts pumping moisture back into the region on Sunday.
Sunday Night Into Monday: Severe Threat
Moisture begins to build on Sunday, March 15, 2026, which will bring scattered showers and a few thunderstorms by the afternoon. The real concern arrives late Sunday night into Monday, March 16, 2026, when a more organized line of storms is expected to move through.
The Storm Prediction Center has outlined an enhanced severe weather outlook for parts of the Southeast in that time frame, with damaging straight-line winds and isolated tornadoes highlighted as the primary threats. Watches and warnings are possible as the system moves through. If you have evening or early-morning plans, it is smart to have an indoor backup and to keep wireless emergency alerts turned on.
Monday Night Into Midweek: Sudden Cold Snap
Once the front sweeps through, temperatures drop hard. By Monday night, lows are forecast to tumble near 27F, with widespread sub-freezing mornings likely on Tuesday and Wednesday, March 17 and 18, 2026. That sets up a serious threat to early spring vegetation and any unprotected crops that have already started to grow.
Expect blustery northwest winds and daytime highs stuck in the 40s on Tuesday. Gardeners should cover vulnerable plants, pet owners will want to bring animals indoors, and commuters should be cautious on early-morning drives if any surfaces stay slick or icy.
